GAGE-ROLLER FOR SAW-MILLS.

SPECIFICATION forming part of Letters Patent No. 440,387, dated November 11, 1890.

Application filed May 13, 1890- Serial No. 351,627. (No model.)

T0 to whom it may concern.-

Be it known that I, SAMUEL BARTLEY, of Bartley, in the county of Morris and State of New Jersey, have inventedacertain new and .useful Improvement in Gage-Rollers for Saw- Mills, of which the following is a specification.

My invention relates to animprovementin gage-rollers for saw-mills, the object being to provide a more substantial device of this character than has hitherto been in common use and one which may be operated and adj usted with greater facility and correctness.

With these ends in View my invention consists in certain features of construction, as will be hereinafter more fully described, and the novelty pointed out in claims.

In the accompanying drawings, Figure 1 represents a gage-roller in vertical section, its support being shown in elevation; and Fig.2 is a top plan view of the upper bearing and clamp, the hand=whee1 and dial being removed.

A represents the bed-piece, provided with an upwardly-projecting rib or head a, the latter being provided along its side with a series of rack-teeth ct. On the bed-piece A the base portion b of an upright B is mounted so as to slide freely along the upper face of the bed-piece in proximity to the rack a. The said sliding upright B is provided with a vertical hearing I) in its lower portion near its front edge, in which bearing the lower end of the vertical shaft G is mounted, the said shaft projecting through the bearing 1) and having fixed thereon a pinion c, intermeshing with .the rack ct. The slide B is further provided at its top with a bracket D, one branch of which d is secured to the upper portion of the slide by means of a screwbolt passing through a hole in the branch (2 and screwing into a tapped hole in the slide B. The said bracket D is provided at a point directly above the bearing 1) at the base of the slide with a bearing (1 in which the upper portion of the shaft 0 is mounted and through which it extends. The bracket is also provided with an annular recess d? in its upper face at the end of the bearing (1 and eccentric thereto. In such recess d an annular cam E is seated and provided with a handle 6 for rocking it. There is preferably provided at the margin of the annular recess 01 an opening (1 through the wall surrounding the said recess, through which opening the handle 6 projects, thereby enabling the upper face of the cam E to rest flush with the upper face of the bracket D.

The shaft 0 is provided at its upper end with a hand-wheel F, by means of which it may be rotated to carry the slide B along the bed-piece through the engagement ofthe pinion c with the rack to, and a dial-plate f is secured to the shaft 0 below the handwheel F to indicate the distance the slide traverses. A roller G is provided with bearings g at its upper and lower ends, by means of which it is loosely mounted on the shaft C between the upper and lower bearings of the shaft in position to rotate by engagement with the timber at all times. By the above construct-ion, when the slide has been moved to the desired position by turning the hand-wheel F it may be securely looked in position by a slight rotary movement of the cam E, which will cause it to wedge between the shaft and the wall of the recess (2 hat I claim is 1. In a gage-roller, the combination of a bed-piece provided with a rack, a slide free to move along the bed-piece, a shaft journaled in suitable bearings in the slide, a roller free to rotate on the shaft, means for rotating the shaft, and a clamping device for locking the shaft, substantially as set forth.

2. In a gage-roller, the combination, with a slide, a vertical shaft journaledin bearings in the slide, the said slide being provided with a recess in proximity to the shaft, of a cam seated in said recess surrounding the shaft, means for rotating the shaft, and means for rocking the cam, substantially as set forth.

3. The herein-described gage-roller, comprising a bed-piece provided with a rack, a slide free to move along the bed-piece and provided with an upper and a lower bearing, the said slide being formed in two separable parts, the said bearings being formed the one in one of the parts and the other in the shaft, means for rotating the shaft, and the other part, a vertical shaft mounted in means for actuating the cam, substantially as said bearings and provided with a pinion in set forth.
